Embodiment Construction

[0022] figure 1 It is a block diagram of a smart grid wireless communication encryption method based on a dynamic key, showing the basic framework of the communication encryption process between any sending node and receiving node in the smart grid wireless communication network.

[0023] Below to figure 2 As an example to illustrate the analysis method of data frame transmission characteristics based on the wait-stop mechanism:

[0024] The analysis of the transmission characteristics of the data frame mainly shows that the retransmission flag is set according to the sending and receiving of the data frame under the stop mechanism, and the process of sending the data frame sequence and receiving the data frame sequence is established based on this. Based on the data packet retransmission mechanism to analyze the transmission characteristics of data frames, the data frame analysis results mainly include three types, namely (1) the sending node successfully sends and the rec...

Abstract

The invention discloses a smart grid wireless communication encryption method based on a dynamic key. A wireless communication node in a smart grid analyzes a data transmission characteristic in the process of wireless communication by observing a communication data frame based on a data retransmission mechanism, and a dynamic key is generated to encrypt and decrypt communication data. By the method, the security of the wireless communication in the smart grid can be effectively improved and computing overhead is reduced.

Description

Technical field: [0001] The invention relates to the technical field of smart grid security communication, in particular to a smart grid wireless communication encryption method using a dynamic key. Background technique: [0002] Smart grid uses information network technology to monitor and optimize the power generation, power distribution and power consumption equipment in the power network in real time, so as to achieve energy saving, emission reduction and other goals. How to ensure the security and concealment of data and control commands in the power network during transmission is the basis for the stable operation of the smart grid. At present, the smart grid mainly guarantees the security of wired communication through the establishment of a dedicated network; in wireless communication, it mainly uses various encryption algorithms to encrypt data and control commands, and then transmits ciphertext to prevent malicious acts such as eavesdropping and tampering. However...
